Chelsea could be without defender Marcos Alonso for their FA Cup semi-final against Southampton.
FA chiefs are reviewing footage of the Spaniard’s challenge on Shane Long as the Blues came from behind to beat Saints in the Premier League on Saturday.
His studs-up tackle went unpunished as a three-goal blitz from Antonio Conte’s side earned all three points and plunged Southampton further into the relegation mire.
Saints had held a 2-0 lead, and boss Mark Hughes called for retrospective action after the game.
“It was a poor challenge, it should have been a red card in my view,” he said. “The disappointment was the officials didn’t see it, they were all within a 10 to 15 metre radius. One of them should have seen it.
“It was a poor tackle, and one that could have been more severe for Shane. Thankfully he’s just about okay, but he’s been raked down the calf.
“Chelsea down to 10 men, it could have put a different complexion on things. Referees have got to get them right – maybe that’s why they’re not in the World Cup this year.
“You’ve seen Shane for years and years, he’s an honest player, he doesn’t go down unless he’s injured. He was really angry after the game because it was a poor challenge.
“I don’t think he was booked, so maybe people need to look at that again, retrospectively.
“We’re not here to accuse people, and no sour grapes, but a decision needs to be made on that because it’s not acceptable.”
